Dog bite statistics ::

Each day nearly 1,000 U.S. citizens require emergency care treatment for serious dog bite injuries.1 Annually, about 12,480 citizens are hospitalized due to dog bite injuries.2 The below statistics and studies examine injury occurrence and the breeds of dogs most likely to inflict severe and fatal injuries. Reviewing Quick Statistics and recent Dog Bite Studies are good starting points. Also see our report that reviews Level 1 trauma center studies from 2011 to present.

Quick statistics

A collection of national nonfatal and fatal dog bite statistics and study-specific statistics. Data include the number of people injured and killed by dogs each year, hospitalization rates for dog bite injuries, costs associated with dog bite injuries, single and combined year dog bite-related fatality statistics, as well as national and worldwide breed-specific law statistics. Sources of these statistics are government bodies, medical researchers, insurance and nonprofit organizations.

Areas within Quick Statistics are reviewed and updated each year. The most recent dog bite study based on federal data was published in 2020 (See all Government dog bite studies).

View literature reviews of retrospective medical studies (2011 to present) and (2009 to 2016) examining dog bite injuries in Level 1 trauma centers across major U.S. geographical regions. Current dog bite fatality studies and studies examining the effectiveness of breed-specific legislation are listed as well. Most studies listed on this page are open access. Sources are peer reviewed medical science journals, studies by government bodies and nonprofit organizations.
